This patchset adds the missing pieces to make the Freescale DCU DRM driver work on Freescale Vybrid. Foremost, it adds support for the timing controller (TCON) module. The module is between the Display Controller and the actual output pins. It allows to alter the timings for RAW TFT displays, but can also operate in a bypass mode. This change has only support for the bypass mode. Earlier variants of the DCU DRM driver configured the TCON module in bypass mode, however this has been removed and postponed. The last variant with the TCON code was v9: https://lkml.org/lkml/2015/7/13/242 This change is an attempt to implement a proper driver. Ideas have been taken from the sun4i Tcon driver: https://lkml.org/lkml/2015/10/30/369 The patchset depends on my fsl-dcu fixes patchset: https://lkml.org/lkml/2015/11/18/953 Stefan Agner (4): ARM: dts: vf610: add display nodes ARM: dts: vf610-colibri: enable display controller ARM: clk: vf610: add TCON ipg clock drm/fsl-dcu: add TCON driver .../devicetree/bindings/display/fsl,dcu.txt | 4 + .../devicetree/bindings/display/fsl,tcon.txt | 18 +++ arch/arm/boot/dts/vf-colibri-eval-v3.dtsi | 16 +++ arch/arm/boot/dts/vf-colibri.dtsi | 33 +++++ arch/arm/boot/dts/vfxxx.dtsi | 18 +++ drivers/clk/imx/clk-vf610.c | 3 + drivers/gpu/drm/fsl-dcu/Makefile | 3 +- drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c | 6 + drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.h | 1 + drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c | 11 ++ drivers/gpu/drm/fsl-dcu/fsl_tcon.c | 134 +++++++++++++++++++++ drivers/gpu/drm/fsl-dcu/fsl_tcon.h | 37 ++++++ include/dt-bindings/clock/vf610-clock.h | 4 +- 13 files changed, 286 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/fsl,tcon.txt create mode 100644 drivers/gpu/drm/fsl-dcu/fsl_tcon.c create mode 100644 drivers/gpu/drm/fsl-dcu/fsl_tcon.h -- 2.6.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
